Hugo, Jane, Zahra, Scarlette, Jannette, and Medea jogged for quite a long time, yet they still haven't met any other patients. The countdown of two minutes signified the start of the danger, and its end should also signify the end of the dangers and the final phase.
Everyone in the group was sure that the two minutes had passed, it should be relatively safe now to continue their journey.
Hugo signaled for the others to temporarily rest and they all took a turn towards a nearby bathroom. The bathroom was for males, but no one really cared about decorum or conventions at this point in time. All of them only had a single wish at this moment.
It was to get out of this place as soon as possible.
Then, if that was true... Why did Hugo lead them to the bathroom?
Well obviously, it was because he realized that the others were running out of juice.
